The BCM67142 from Broadcom is an Integrated Wi-Fi 8 Chip that operates in the 2.4 GHz and 5 GHz bands. It is a low-cost solution optimized to provide dual-band, high-throughput connectivity while maintaining excellent power efficiency for 802.11bn access points, repeaters, WLAN clients, and other bandwidth-intensive applications. This chip integrates 2.4/5 GHz radios with MAC/PHY functionality, on-chip power amplifiers, an AXI backplane, and a PCIe 2L Gen3 interface in a single form factor, simplifying design and reducing the PCB footprint. It supports 160 MHz (5 GHz band) and 40 MHz (2.4 GHz) channel bandwidths on 3x3 and 4x4 MIMO configurations.
The BCM67142 Wi-Fi 8 chip supports a variety of features to enhance capacity – dynamic sub-band operation, multi-AP and inter-AP coordination, and dynamic bandwidth expansion. It also uses advanced LDPC codes with new UHR MCS rates and unequal modulation, along with ELR for extended range. This chip incorporates digital pre-distortion with advanced eco-modes and power optimization schemes to ensure ultra-low energy consumption in high-performance networking devices. It is available in an SMT chip-scale package.
